Can You Plant Trees on Septic Field?

Septic tanks are essential for homes and properties that don't have access to municipal sewage systems. They work by treating wastewater and returning it to the ground via a drainage system or leach field. The leach field is an essential part of the system and consists of perforated pipes that are laid out underground. When the wastewater leaves the septic tank, it goes into the leach field and is purified by bacteria before being absorbed by the soil. However, many homeowners are unaware of what they can and cannot do on their leach field, including planting trees. In this article, we'll answer the question, "can you plant trees on septic field?"

The Risks of Planting Trees on a Septic Field

While it might be tempting to transform your leach field into a lush garden, planting trees over a septic field can pose several risks to your septic system. One of the most apparent risks is that tree roots can damage the pipes and cause leaks in the system, which can lead to costly repair bills. Roots from mature trees can penetrate and clog the perforated pipes and prevent proper wastewater drainage. This can lead to backups in the septic tank, overflowing toilets, and a strong smell of sewage in your yard. Additionally, the weight of the trees and their roots can compress the soil and damage the drainage field, causing it to malfunction or fail entirely.

What to Plant on Your Septic Field

When it comes to planting on your septic field, it's best to avoid planting trees or any other plants with deep root systems. Instead, opt for shallow-rooted plants and grasses that won't damage or clog your leach field. Grasses like fescue, bluegrass, and perennial ryegrass are excellent choices for a septic field, as their roots are shallow and won't interfere with the system. You can also consider planting low-maintenance plants like wildflowers or shrubs that require minimal watering and maintenance. However, it's essential to keep in mind that excessive irrigation can also harm your septic system, so be careful not to overwater your plants.

Taking Care of Your Septic Field

While it's crucial to avoid planting trees on your septic field, proper maintenance is key to ensuring the longevity of your system. You should have your septic system inspected every one to three years, depending on the size of your household and the number of people living in the house. Regular pumping of your septic tank also helps to prevent backups and overflows. Remember to conserve water by fixing any leaks, using high-efficiency appliances, and avoiding excessive use of water. Lastly, avoid flushing anything other than human waste and toilet paper down the toilet, as this can clog your pipes and cause damage to your septic field.

The Bottom Line

Planting trees on your septic field is not recommended, as their roots can cause significant damage to your system. Instead, consider planting shallow-rooted plants and grasses that won't interfere with your leach field. Remember to take good care of your septic system by having it inspected regularly, conserving water, and avoiding flushing harmful materials down the toilet. By following these simple steps, you can ensure that your septic system remains in good condition and serves you well for years to come.
